Buffer Hit Ratio | Oracle | The buffer cache hit ratio calculates how | |
|
|
| often a requested block has been found |
|
|
| in the buffer cache, without requiring disk |
|
|
| access. If the ratio is less then 90 percent |
|
|
| investigate further. You may need to |
|
|
| increase cache size by increasing |
|
|
| db_block_buffer(8i) or |
|
|
| db_cache_size(9i). |

Bytes Transferred | Engenio Storage Systems | Bytes transferred on a drive. | |
|
|
|
|
Bytes Transmitted | • | Storage Systems | Number of bytes transmitted by the port |
(MB/Sec) | • Host (port for HBA | per second | |
|
| card) |
|
| • NAS Filer (IP Port) |
| |
| • | Switch Port |
|
|
|
|
|
Bytes Received | • | Storage Systems | Number of bytes received by the port per |
(MB/Sec) | • Host (port for HBA | second | |
|
| card) |
|
| • NAS Filer (IP Port) |
| |
| • | Switch Port |

CPU Usage | Sybase | Percentage of the Sybase CPU being | |
Percentage (%) |
|
| used. For example, if this monitoring |
|
|
| appears pegged at 100 percent, this |
|
|
| means one or more Sybase databases on |
|
|
| the host are using 100 percent of the |
|
|
| Sybase CPU, not the host CPU. The host |
|
|
| CPU could be pegged at 60 percent, |
|
|
| while the Sybase CPU is pegged at 100 |
|
|
| percent. |
